Description

  The present invention provides preset control means for performing channel preset for specifying area information based on current position information acquired by position information acquisition means and setting a channel frequency so that a channel of the specified area information can be received. The present invention relates to a portable terminal device equipped with a television receiver.

  Recently, mobile phones equipped with television receivers are becoming popular. In particular, in terrestrial digital broadcasting, so-called 1-segment broadcasting using one segment allocated for mobile (mobile) has started, and mobile phones equipped with television receivers will rapidly spread in the future. It is thought to do.

  In this case, the problem is that the frequency of the broadcasting station assigned to each channel differs depending on the region. Therefore, for example, when a user who has a mobile phone goes from Osaka to Tokyo on a business trip or the like, it passes through several areas with different frequencies, so the reception frequency of the TV receiver each time. Needs to be reset to the channel frequency assigned to the region where it is moving. For this reason, conventionally, portable terminal devices and the like that automatically perform channel switching (setting) for each region have been proposed (see, for example, Patent Documents 1 to 4).

  In Patent Document 1, when the power is turned on, the location registration is performed in the base station, the location information from the base station is received, and the control unit receives the location information from the base station to the regional channel storage unit. A configuration is shown in which a region code is collated and a receivable channel is displayed on a display unit, and a configuration of a mobile terminal device using location information obtained by GPS (Global Positioning System) instead of location information from a base station is described. Has been.

  Patent Document 2 discloses a location information acquisition unit that acquires information about a location where a receiver is located, and a terrestrial broadcast in a terrestrial broadcast area that is specified by the location acquired by the location information acquisition unit. Channel selection information acquisition means for acquiring channel selection information, and automatic channel selection control for sequentially selecting each broadcast frequency of terrestrial broadcast in the terrestrial broadcast area based on the channel selection information acquired by this channel selection information acquisition means Terrestrial digital broadcasting comprising: means and a selection target presetting means for selecting and presetting a broadcast whose reception state is a predetermined quality or higher among broadcasts selected by the automatic channel selection control means The configuration of the receiver is described.

  In Patent Document 3, the current position information is acquired by a position acquisition service such as GPS or PHS, the map number corresponding to the current position is checked from the regional database, and the corresponding map number is set to the variable Mo. To store. Then, in the list of effective broadcasting stations with the map number Mo, a configuration of a broadcast receiving apparatus that sequentially registers channels (reception frequencies) having better sensitivity than the specified value in the channel memory in order of increasing sensitivity (see paragraph [0056], FIG. 17 and the like). ) Is described.

Further, Patent Document 4 includes a broadcast map that is stored in a predetermined section in which positions of broadcast stations and their broadcast frequencies are associated with each other, and automatic position measurement means such as GPS. A configuration of a broadcast channel selection apparatus is described in which a broadcast station map is searched based on a section corresponding to the position and a broadcast frequency is set.

  According to each of the above Patent Documents 1 to 4, when the reception area of each channel changes due to movement of the mobile terminal device or the like, the area code is acquired based on the position information acquired from the GPS or the like, for example, It is possible to automatically channel preset to local channel frequencies.

  However, in Patent Documents 1 to 4, when a user who has a portable terminal device is on a subway, for example, and location information cannot be obtained from GPS or the like, a region code cannot be obtained. There was a problem that could not be done. That is, even if the reception area of each channel changes due to movement of the mobile terminal device or the like, there is a problem that it cannot be preset to the channel frequency of the area unless position information can be acquired from GPS or the like.

  In Patent Documents 1 to 4, when the position information can be acquired, the area code is acquired based on the position information and automatically preset to the channel frequency of the area. For this reason, there has been a problem that if the acquisition of the position information is not accurate for some reason, it may be set to the wrong region code.

The present invention has been devised to solve such problems, and the first object is to require channel presets in consideration of the reception state of the television signal at that time even when acquisition of position information fails. It is an object of the present invention to provide a television receiver-equipped mobile terminal device capable of accurately determining whether or not there is sex and processing a channel preset procedure interactively. A second object of the present invention is to provide a television receiver-equipped mobile terminal device that can perform more accurate channel presetting by determining the accuracy of acquired position information.
Is to provide.

  In order to solve the above problems, a portable terminal device with a built-in television receiver according to the present invention includes position information acquisition means for acquiring a current position, and area information storage means for storing information for each area of a receivable channel. A channel for specifying the area information stored in the area information storage unit based on the current position information acquired by the position information acquisition unit and setting the channel frequency so that the channel of the specified area information can be received. A television receiver-equipped portable terminal device having preset control means for performing presetting, further comprising a judging means for judging whether or not a television signal is received; When the current position information acquisition by the position information acquisition means fails, the control means If the determination means determines that the television signal has not been received, the user confirms whether or not the channel preset by manual input has been performed, and the user receives the regional information. It is characterized in that channel preset is performed when input.

  That is, according to the television receiver-mounted mobile terminal device of the present invention, when the acquisition of the position information fails, first, it is determined by the determining means whether or not the television signal can be received at that time, In the case where it is determined that it has not been received, it is configured to confirm whether or not the channel preset is performed manually by the user (display a confirmation message). For example, the position information cannot be acquired and the television signal cannot be received in various cases such as when the user is in a building, on a subway, or when a car is traveling in a tunnel. The situation can be considered. In this case, when the user inputs the area information manually, the preset control means sets the channel preset so that the channel of each station in the corresponding area stored in the area information storage means can be received. carry out.

  Further, according to the present invention, when it is determined that the television signal cannot be received, the procedure may be shifted to a more detailed procedure. That is, in the power-on state of the television receiver, the preset control means confirms the judgment result in the judgment means when the position information acquisition means fails to obtain the current position information, and the judgment means confirms the television signal. If it is determined that the reception state has not been received, a confirmation message as to whether or not to end the reception state is displayed next. If the user chooses not to end the reception state in response to the confirmation message, a confirmation message is displayed next to the user regarding whether or not the channel preset is performed manually. Channel presetting may be performed when the user inputs regional information in response. That is, by displaying a confirmation message as to whether or not to end the reception state, for example, when the user determines that it is natural that the user cannot watch because the user is in the building, the reception state can be ended as it is. That's fine. In addition, even if the reception is possible but the reception is not possible, and the user does not select the end of the reception state, it is considered that he / she wants to watch as it is. What is necessary is just to continue television reception as it is. On the other hand, when the user inputs the area information in response to the confirmation message, the preset control means sets the channel preset so that the channel of each station in the corresponding area stored in the area information storage means can be received. To implement.

  Further, according to the television receiver-equipped portable terminal device of the present invention, the preset control means can detect the television signal by the judgment means even when the position information acquisition means fails to acquire the current position information. Is determined to have been received, the initial purpose of viewing a television program has been achieved, and the process is terminated.

  The television receiver-equipped mobile terminal device of the present invention includes a position information acquisition unit that acquires a current position, a region information storage unit that stores information for each region of a receivable channel, and the position information acquisition. A preset for identifying the area information stored in the area information storage means based on the current position information acquired by the means and setting a channel frequency so that the channel of the specified area information can be received In the television receiver-mounted portable terminal device comprising the control means, the preset control means is configured to obtain the current position acquired by the position information acquisition means at predetermined time intervals when the television receiver is in a power-on state. Calculate regional information based on the information and determine whether the calculated regional information matches the previously calculated regional information If there is a match, it is checked whether or not the number of matches is n times or more set in advance. If it is n times or more, the calculated area information is confirmed and the determined area information is It is characterized in that it is confirmed whether or not the TV receiver matches the set area information, and if it does not match, channel preset is performed.

  In this way, by repeating the determination of whether or not the calculated area information matches the previously calculated area information n times or more, if the location information acquisition is not accurate for some reason, It is possible to prevent the occurrence of problems such as performing channel presets.

  In this case, when the channel preset is performed, the preset control means may be switched to a channel of a broadcasting station similar to the broadcasting station of the channel currently being received (that is, a channel of an affiliated station). In this way, when a channel preset is performed, the channel is automatically switched to the affiliated channel of the channel that was previously viewed, so that the user can continue to view the same program without having to perform channel switching operations one by one. It becomes possible to do.

  Note that (6) the position information acquisition means can acquire current position information from GPS.

  According to the portable terminal device with a built-in television receiver of the present invention, when acquisition of position information fails, it is first determined whether or not a television signal can be received at that time, and if it cannot be received. When it is determined, it is configured to confirm whether or not the channel preset is performed manually by the user. In other words, even if location information acquisition fails, it can be determined that the broadcasting area has changed because the television signal has not been received. In this case, the user can manually input the area information to obtain the corresponding area. The channel preset can be performed so that the channels of the respective stations can be received.

  In addition, according to the portable terminal device with a built-in television receiver of the present invention, the determination of whether the calculated area information matches the previously calculated area information is repeated n times or more, so that the acquisition of the position information is for some reason. If it is not accurate, it is possible to prevent the occurrence of problems such as channel preset based on wrong area information. In addition, when a channel preset is performed, the channel is switched to the channel of the broadcasting station of the same example as the broadcasting station of the channel currently being received (that is, the channel of the affiliated station), so the user switches the channel after each channel preset. Even if no operation is performed, the same program can be continuously viewed.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a functional block diagram showing an electrical configuration of a main part of a television receiver-equipped mobile phone which is an embodiment of the television receiver-equipped portable terminal device of the present invention. However, in the present embodiment, since the video and audio signal processing by the television receiver is a well-known process, a simple functional block is shown here as a TV signal processing unit. In addition, since signal processing related to telephone calls and mails by a cellular phone is a well-known process, a simple functional block is shown here as a signal processing unit on the telephone side.

  That is, the television receiver-equipped mobile phone of this embodiment includes a telephone control system 10 that controls functions as a mobile phone such as a telephone function and a mail function, and a TV control system that receives a television signal of digital / analog broadcasting. 20, a telephone side microcomputer 11 that controls the entire telephone control system 10 and a TV side microcomputer 21 that controls the entire TV control system 20 are bidirectionally connected by a bus communication 35.

  That is, the TV control system 20 includes a tuner circuit 22 that receives a digital / analog broadcast television signal, and an output of the tuner circuit 20 is connected to a TV signal processing unit 24. The output of the TV signal processing unit 24 is connected to the display unit 13 such as a liquid crystal display via the switching circuit 15. The output of the TV signal processing unit 24 is connected to the internal speaker 27 via the amplifier 26. The TV signal processing unit 24 includes an OSD circuit 24a that displays a setup screen for performing various settings for television reception. The TV signal processing unit 24 is controlled by the TV-side microcomputer 21, decodes the television signal received via the tuner circuit 22 into a video signal and an audio signal, displays the video signal on the display unit 13, and internally stores the audio signal. Output from the speaker 27.

  The TV-side microcomputer 21 is connected to a position information acquisition unit 28 that acquires the current position of the mobile phone based on a signal from a GPS satellite (not shown) received by the antenna 28a. The TV-side microcomputer 21 performs channel preset processing, which is a feature of the present invention, based on the current position information acquired by the position information acquisition unit 28. The TV-side microcomputer 21 is connected to a TV-side memory unit 29, and the TV-side memory unit 29 stores area information at the time of channel presetting in advance. That is, information on receivable channels is stored for each region. Since this area information is conventionally known information, detailed description thereof is omitted here.

  On the other hand, the telephone control system 10 includes a wireless communication unit 12 that communicates with a communication terminal device such as another mobile phone via a wireless base station. The wireless communication unit 12 is connected to the telephone-side signal processing unit 14. ing. The output of the telephone signal processing unit 14 is connected to the display unit 13 via the switching circuit 15. The telephone-side signal processing unit 14 includes an OSD circuit 14a that displays a menu screen for performing various settings and inputs related to a telephone function, a mail function, and the like. The telephone side signal processing unit 14 is controlled by the telephone side microcomputer 11. In addition, the telephone side microcomputer 11 stores various information such as an operation unit 12 in which dial keys and function keys operated by a user are arranged, a transmission / reception unit 16 including a microphone and a speaker, and a telephone book and an e-mail address. A telephone-side memory unit 17 is connected.

  The telephone-side microcomputer 11 controls the operation of the telephone control system 10 and the TV control system 20 based on various operation signals input from the operation unit 12. That is, in this embodiment, all control signals including power on / off of the TV control system 20 are transmitted to the TV side microcomputer 21 through the telephone side microcomputer 11. Further, switching control of the switching circuit 15 is also performed by the telephone side microcomputer 11.

  In the above configuration, the TV-side microcomputer 21 is stored in the TV-side memory unit 29 based on the current position information acquired by the position information acquiring unit 28 when the TV receiver is turned on and after that. The channel preset is performed to identify the area information and set the channel frequency so that the channel of the identified area information can be received. In this case, if acquisition of the current position information fails, a channel preset by manual input is guided through an interactive procedure.

  Hereinafter, the processing procedure until the channel preset by the TV-side microcomputer 21 will be specifically described with reference to the flowcharts shown in FIGS.

  When the power of the television receiver is turned on, the TV-side microcomputer 21 reads the current position information acquired at regular intervals by the position information acquisition unit 28 (step S1). Here, as the fixed time, for example, a time of about several seconds to several tens of seconds is preferable.

  The TV-side microcomputer 21 determines whether or not the positioning is successful based on the read current position information (step S2). Here, when the user carrying the mobile phone is in a state where it cannot receive a signal from the GPS, for example, in a building or on a subway, the determination in step S2 is No. . Therefore, in this case, the TV side microcomputer 21 proceeds to step S3 and confirms whether or not presetting of a receivable channel has already been manually performed. This confirmation is confirmed by the on / off state of the manual input flag. As a result, when the manual input flag is turned on (when it is determined Yes in step S3), the manual channel preset has already been completed, and thus the process is terminated.

  On the other hand, if the manual input flag is off (if determined No in step S3), it is next determined whether a television signal can be received on the current channel (step S4). . As a method for determining whether or not a television signal can be received, it is possible to determine, for example, how much noise is included in the audio signal. It is possible to adopt. As a result, when it is determined that the television signal can be received (when determined Yes in step S4), the initial purpose of watching the television is achieved even if the position information is not acquired. Therefore, in this case, the process is terminated without moving to the channel preset process.

  On the other hand, when it is determined that the television signal cannot be received (when it is determined No in step S4), whether to end the reception state, that is, whether to turn off the power of the television receiver. Is displayed on the display unit 13 (step S5). In this way, by displaying a confirmation message as to whether or not to end the reception state, for example, when it is natural that the user cannot watch because the user is in the building, the reception state is left as it is. Just finish. That is, when the user selects to turn off the power of the television receiver in response to the confirmation message (for example, when a button labeled “Yes” displayed with the message is operated), the television receiver The receiver is turned off (step S6), and the process is terminated.

  On the other hand, when the user selects not to turn off the power of the television receiver in response to the confirmation message (for example, when a button labeled “No” displayed along with the message is operated), Then, a confirmation message is displayed on the display unit 13 as to whether or not to perform channel preset by manual input to the user, that is, whether or not to input regional information by itself (step S7). Then, when the user selects the input of the area information in response to the confirmation message (for example, when the button labeled “Yes” displayed with the message is operated), the determination in step S7 Therefore, the TV-side microcomputer 21 displays an input screen for inputting area information on the display unit 13. That is, an area information input screen to be selected from the menu screen is directly displayed. When the user inputs area information manually according to the display screen (step S8), the TV-side microcomputer 21 can receive the channel of each station in the corresponding area stored in the TV-side memory unit 29. Then, the channel preset is performed (step S9), and then the manual input flag is turned on (step S10), and the process is terminated.

  On the other hand, when the user selects not to input the area information in response to the confirmation message (for example, when a button labeled “No” displayed together with the message is operated), “No” is set in step S7. Therefore, the process does not proceed to the channel preset process. In this case, the manual input flag is turned on (step S10), and the process ends. That is, it is considered that the user does not manually input the area information, so that the user desires to view it as it is. In this case, even if the next positioning fails, the determination in step S3 is No. Thus, the processing is ended after the manual input flag is turned on so that the processing in steps S4 to S9 is not repeated again.

  Next, returning to step S2, if the TV-side microcomputer 21 has succeeded in positioning based on the read current position information, the operation proceeds to step S11, for example, the manual input flag turned on in step S10. Turn off.

  Then, the area information is calculated based on the acquired current position information (step S12), and it is determined whether or not the calculated area information matches the previously calculated area information (step S13). As described above, when the power of the television receiver is turned on, the TV-side microcomputer 21 reads the current position information acquired at regular intervals by the position information acquisition unit 28 (step S1).

  As a result, when the calculated area information is the same as the previous area information (when it is determined Yes in step S13), a counter (not shown) for counting the number of matches (for example, an internal not shown of the TV-side microcomputer 21). 1) (step S14), and the area information calculated this time is stored in a predetermined area of the TV-side memory unit 29 (step S16). In this case, if the previously calculated area information is stored in a predetermined area of the TV-side memory unit 29, it is updated and stored in an overwritten form.

  On the other hand, when the calculated area information is different from the previous area information (when it is determined No in step S13), a counter (not shown) for counting the number of matches is cleared to 0 (step S15), and this time calculation is performed. The area information thus saved is stored in a predetermined area of the TV side memory unit 29 (step S16). If the current reading is the first reading after the television receiver is turned on, the area information calculated last time does not exist, so the determination result in step S13 is necessarily No. In this case, if the previously calculated area information is stored in a predetermined area of the TV-side memory unit 29, it is updated and stored in an overwritten form.

  Next, the TV-side microcomputer 21 checks whether or not the count value of the counter has reached a preset count value n (for example, n = 5 is set) (step S17). That is, it is confirmed whether or not the previously calculated area information and the currently calculated area information are matched n times (five times).

  As a result, if the number of matches has not reached n (if determined No in step S17), the process ends.

  On the other hand, when the number of matches has reached n (when it is determined Yes in step S17), it is confirmed that there is no error in the calculated area information. Then, the area information of the television receiver is determined (step S18). Then, the determined area information is compared with the area information set at the time of the previous power-off of the television receiver (step S19).

  As a result, when the area information determined this time is the same as the area information set last time (when it is determined No in step S19), the television reception is continued and the process is terminated. On the other hand, when the region information determined this time is different from the region information set last time (when determined Yes in step S19), the TV-side microcomputer 21 performs channel preset (step S20). Then, after performing the channel preset, the channel is switched to the channel of the broadcasting station similar to the broadcasting station of the channel currently being received (that is, the channel of the affiliated station) (step S21). In this way, when a channel preset is performed, the channel is automatically switched to the affiliated channel of the channel that was previously viewed, so that the user can continue to view the same program without having to perform channel switching operations one by one. It becomes possible to do.

  Note that the TV-side microcomputer 21 repeatedly performs the processing of the above steps until the power of the television receiver is turned off, that is, while the television signal is being received. However, every time a predetermined time (for example, 30 minutes) elapses after the processing of each step described above is performed when the power is turned on and the channel preset is performed, or after confirming that the area information matches. In addition, the processing of each of the above steps may be performed. Thereby, the power consumption of a mobile telephone can be reduced even a little.
